Treatment of Gastritis Symptoms
Proton pump inhibitors (PPIs) are the first-line treatment for gastritis symptoms, with high-potency options like esomeprazole 20-40 mg twice daily or rabeprazole 20 mg twice daily being most effective for symptom relief and mucosal healing. 1
Initial Management Approach
First-Line PPI Therapy
- Start with high-potency PPIs rather than lower-potency options for optimal symptom control 1
- Avoid pantoprazole when possible due to significantly lower potency (40 mg pantoprazole = only 9 mg omeprazole) 1
- Take PPIs 30 minutes before meals to maximize effectiveness—inadequate timing is a common pitfall that reduces therapeutic benefit 1
- Continue treatment for 4-8 weeks depending on symptom severity and underlying cause 2, 3
H. pylori Testing is Mandatory
- All patients with gastritis must be assessed for H. pylori infection before finalizing treatment strategy 4, 1
- Use non-invasive testing: urea breath test or monoclonal stool antigen test 1
- If H. pylori is positive, eradication therapy is mandatory and fundamentally changes the treatment approach 4
H. pylori-Positive Gastritis Treatment
Preferred Eradication Regimen
- Bismuth quadruple therapy for 14 days is first-line due to increasing antibiotic resistance 1
- High-potency PPI (esomeprazole or rabeprazole) twice daily
- Bismuth subsalicylate
- Metronidazole
- Tetracycline
- Concomitant 4-drug therapy is an alternative when bismuth is unavailable 1
- Higher-potency PPIs improve H. pylori eradication rates compared to standard-dose omeprazole 1
Critical Follow-Up
- Confirm successful eradication using non-serological testing (not antibody tests) after completing therapy 4, 1
- Failure to confirm eradication is a major pitfall that leads to persistent infection and complications 1
- Eradication heals gastritis and prevents progression to atrophic gastritis, particularly important in patients requiring long-term PPI therapy 4, 1
Special Clinical Scenarios
NSAID-Associated Gastritis
- Discontinue NSAIDs immediately if possible 1
- If NSAIDs must be continued:
- Misoprostol (synthetic PGE1) reduces NSAID-associated gastric ulcers by 74% but causes diarrhea, abdominal pain, and nausea limiting its use 1
Atrophic Gastritis Considerations
- Long-term PPI use in H. pylori-positive patients accelerates progression to corpus-predominant atrophic gastritis 4, 1
- This underscores the critical importance of H. pylori eradication before initiating chronic PPI therapy 4
- Evaluate for vitamin B-12 and iron deficiencies in all patients with atrophic gastritis, especially corpus-predominant disease 4, 1
- Consider checking antiparietal cell and anti-intrinsic factor antibodies if autoimmune gastritis is suspected 4, 1
- Screen for autoimmune thyroid disease in patients with confirmed autoimmune gastritis 4, 1
Surveillance Requirements
- Patients with advanced atrophic gastritis (Stage III/IV OLGA or OLGIM) require endoscopic surveillance every 3 years 4
- Obtain biopsies from body and antrum in separately labeled jars when atrophic changes are present 4
- Autoimmune gastritis patients need individualized surveillance intervals, typically every 3-5 years 4
Adjunctive Symptom Management
Breakthrough Symptoms
- Antacids provide rapid, temporary relief and can be used on-demand for breakthrough symptoms while awaiting PPI effect 1
- H2-receptor antagonists (ranitidine, famotidine) provide faster symptom relief than PPIs but are less effective for mucosal healing 1, 3
- H2RAs are particularly less effective for gastric ulcers compared to duodenal ulcers 1
Common Pitfalls to Avoid
- Inadequate PPI dosing or premature discontinuation before completing 4-8 weeks of therapy 1
- Failure to test for H. pylori in all gastritis patients 1
- Relying on symptom resolution without confirming H. pylori eradication—this leads to persistent infection 1
- Using low-potency PPIs (pantoprazole) when high-potency options are available 1
- Incorrect PPI timing—must be taken 30 minutes before meals 1
- Failure to evaluate for vitamin B-12 and iron deficiencies in atrophic gastritis 4, 1
